I wanted a pretentious bar car for the living room. Unfortunately these things are very expensive or do not suit my taste, so I built my own creation using 3D printing and cheap aluminium profiles.

Finally finished and complete!

Print Settings

Printer:

Dosent matter

Rafts:

Yes

Supports:

Yes

Resolution:

0.2

Infill:

40%

Filament:

Eryone, Polialchemy PLA

Copper, Alpha Brass


Notes:

Set what your printer can do, higher infill is needed to withstand the pretension of the bolts. Print direction: profile facing sides should be on the bottom for best visuals.

Bill of material ================

Test print some files before buying stuff, a good and accurate printer is required. Maybe settings have to be adjusted for the press fits. A lot of support material is needed on FDM printers...

Hardware store:

  • 20x20 aluminium profiles, I used four each of these lengths:

A: 650mm

B: 450mm

C: 350mm

  • 2 plates, I used 450x350x3 alu sheet metal (B x C), in hindsight i would recomend 4mm Alu or 3mm stainless steel. My bottom plate is bending a little bit...
  • 60 M5 sliding nuts
  • 70 M5x8 screws
  • 8 ballbearings 8x22x7
  • 4 M5x25 countersunk screws (DIN 965)
  • a M5 tap for the lenght A 20x20 profiles
  • optional: 10 hidden corner connectors for 20x20 profiles when printing silk filament with poor layer adhesion. Or just use standard pla filament.

Note: You can use profiles of any length for A,B and C. Just make sure that there is a center hole for the M5 thread.

3d-printed:

  • 6 3-way connectors
  • 4 2-way connectors
  • Plate holder top rear LH
  • Plate holder top rear RH
  • 4 covers, with or without skull
  • 4 lower plate brackets
  • 4 foot assemblies
  • press tools (maybe not needed, try first without it)

Foot assembly:

  • bearing nut
  • foot, print this out of regular pla

Costs: ~140€ + filament

Assembly

Assembling the trolley takes a few hours. Take your time and do not rush...

  1. Tap the lenght A 20x20 profiles at one end, the thread is needed on the bottom.
  2. Screw the M5x25 through one ball bearing and the lower plate brackets on to the threads on the A profiles.
  3. Assemble the foot with the bearing nut and two M5x6 screws. Push the nut in to the bearing, use the press tools for that. Place the wheel (nut and bearing) in the fork of the foot. Use a powertool to cut with the screws into the plastic nut.
  4. Connect the profiles with the 3d printed connectors and the optional hidden corner connectors. This needs more time then you think, be patient and make sure everything is level. Adjust the hight of the upper plate and the cross bars to your liking.
  5. Drill matching holes in the corners of the plates (only two needed for the top plate). An fix the plates to the frame.
  6. Press the assembled feet on the bearing on the lower plate brackets and mount the covers on top of the A profiles.
  7. Place a nice drink on the bar trolley and enjoy.
